Zingel streber
Annex II Priority No Species group Fish Regions Alpine, Black Sea, Continental, Pannonian, Steppic
The streber is a freshwater fish species distributed in central and south-east Europe. It prefers main courses of small to large rivers, in stretches with strong current. Usually on stone bottom. Threats to this species are dams and pollution.
Species found only in Danube catchment area, in Alpine region, Steppic and Black Sea region as well. It is more common in adjacent Continental and Pannonian regions. Assessed as ‘unfavourable-inadequate’ in all regions except Alpine region were status is unknown. The apparant improvement compared to 2007 when two regions where considered unfavourable- bad’`is not a geniun change but an effect of new MS joining the EU and a reestimation of distribution areas.
According to IUCN species is ‘least concern’ both globally and in EU27.

The map shows both Conservation Status and distribution using a 10 km x 10 km grid. Conservation status is assessed at biogeographical level. Therefore the representation in each grid cell is only illustrative.

Knowing that not all changes in conservation status between the reporting periods were genuine, Member States were asked to give the reasons for changes in conservation status. Bulgaria and Romania only joined the EU in 2007 and Greece did not report for 2007-12 so no reason is given for change for these countries. Greek data shown above is from 2001-06. Main pressures and threats reported by Member States
Member States were asked to report the 20 most important threats and pressures using an agreed hierarchical list which can be found on the Article 17 Reference Portal. Pressures are activities which are currently having an impact on the species and threats are activities expected to have an impact in the near future. Pressures and threats were ranked in three classes ‘high, medium and low importance’; the tables below only show threats and pressures classed as ‘high’, for some species there were less than ten threats or pressures reported as highly important.

For species listed in the Annex II of the Directive Member States were asked to report the population size within the Natura 2000 network. The percentage of species population covered by the network was estimated by comparing the population size within the network and the total population size in the biogeographical/marine region.

Most frequently reported conservation measures
For species listed in the Annex II of the Directive Member States were asked to report up to 20 conservation measures being implemented for this species using an agreed list which can be found on the Article 17 Reference Portal. Member States were further requested to highlight up to five most important (‘highly important’) measures; the table below only shows measures classed as ‘high’, for many species there were less than ten measures reported as highly important.

This information is derived from the Member State national reports submitted to the European Commission under Article 17 of the Habitats Directive in 2013 and covering the period 2007- 2012.

iAssessment of conservation status at the European biogeographical level: Current Conservation Status (Current CS) shows the status for the reporting period 2007-2012, Previous Conservation Status (Previous CS) for the reporting period 2000-2006. Reason for change in conservation status between the reporting periods indicates whether the changes in the status were genuine or not genuine. Previous Conservation Status was not assessed for Steppic, Black Sea and Marine Black Sea regions. For these regions the Previous status is therefore considered as ‘unknown’. The percentage of the species population occurring within the biogeographical/marine region (% in region) is calculated based on the area of GIS distribution.
iiPercentage of coverage by Natura 2000 sites in biogeographical/marine region: In some cases the population size within the Natura 2000 network has been estimated using a different methodology to the estimate of overall population size and this can lead to percentage covers greater than 100%. In such case the value has been given as 100% and highlighted with an asterisk (*). The value ‘x’ indicates that the Member State has not reported the species population and/or the coverage by Natura 2000. No information is available for Greece. The values are only provided for regions, in which the occurrence of the species has been reported by the Member States.
